server {
       listen 80 default_server;

       server_name localhost;
       root /app/src;

       error_log  /var/log/nginx/error.log;
       access_log /var/log/nginx/access.log;

       location /api {
           root /app/src;
           index index.php index.html index.htm;
           try_files  $uri /api/index.php$is_args$args;

           location  ~ \.php$ {

                 fastcgi_pass api:9000;
                 include fastcgi_params;
                 fastcgi_split_path_info ^(?:\/api\/)(.+\.php)(.*)$;
                 fastcgi_index index.php;
                 fastcgi_param SCRIPT_FILENAME /app/src/index.php;
             }
       }

                  proxy_pass http://web:80;

                  proxy_set_header Connection 'upgrade';
                  proxy_set_header Host $host;
                  proxy_cache_bypass $http_upgrade;
